The carbon dioxide in the atmosphere produces a greenhouse effect.
Fortunately for us the oceans are so massive that they are taking their time to heat up. The air blows over them and cools. So things don't feel quite so bad.
But the oceans are slowely and constantly warming.
Everything will continue to heat up if we don't remove the atmosphere's massive CO2 overload.
With the carbon dioxide overload we have already created; no amount of emissions reduction; right up to even total curtailment, can stop this continious heating.
It's already way too late for just emissions reduction to work.
We have added, in total, TW0 TRILLIONS TONNES of CO2 to the atmosphere. The oceans have sucked in one trillions tonnes so they're now overloaded.
So ONE TRILLION TONNES is still there. Give farmers an incentive of $10 a tonne for "soil carbon sequestration" and they can suck out the rest.
Then we go biofuels and nuclear.
CLIMATE CHANGE IS TERMINATED
GLOBAL WARMING STOPS
OCEAN TEMPERATURES RESET &
WORLD WEATHER SOON NORMALIZERS
And there is absolutely, no "Option B"
Concentrating on "Emission Reductions" is a callous red herring to protect the agrochemical industries. At best it's just slowing the rate we double glaze the other half of the planet.
I've been hammering this approach since I published the first paper on my concept in 1989. (Coincidently; in March, the same year, a CERN scientist dreamed up the concept of the World Wide Web.)
So first; we have to remove the current excess; and second we stop putting more back in.
Removing it can only be achieved by soaking it into our agricultural soils by increasing the humus content of those soils. It's called soil carbon sequestration. It's explained below. Nothing else will work.
Stopping the adding can only be achieved by a complete change to renewable fuels. For power that's mainly nuclear energy and for transport it's got to be biofuels.
The geocarbon fuel industries have to go out of business.
Or just give up. And if you're over fifty, may be you say "Who cares?".
SOIL So many people ask about it. They say -----
Tell me in a nut shell.
How does soil carbon sequestration work?
How do you take the carbon dioxide out of the air
I'm Allan Yeomans and this is how I often explain it.:
1 Cows eat grass.
2 One bite, and the grass plant immediately sheds a few roots.
3 The cows produce waste.
4 Soil microbes and earth worms eat dead grass roots and cow's waste,
5 Grasses grow best in humus rich soil. So it's full circle, back to the cow.
Hard rock, near the surface, weathers down and becomes “subsoil”. Subsoil is biologically inert. But when humus is created in that subsoil, then it becomes “topsoil”. It's a billion year old process.
The chemistry is straight forward. Both living plant materials and soil humus are about half carbon. Carbon dioxide in the air is about one third carbon. Using carbon dioxide from the air, water from the ground, and sunlight from space, the chlorophyll in a blade of grass, or any other green leaf, manufactures living plant materials.
Herbivores eat grass, carnivores eat herbivores.
And we're omnivores; so we can eat both. "
This links to the explanation on where the concept of soil carbon sequestration originated. The origonsl paper was also entitled "Agricultural Solution to the Greenhouse Effectt "
This link is down. It's being fixed now, Sep 2015. Don't know as yet what went wrong
THE SOIL CARBON SOLUTION ( the only chance we have)
(Added the below today Jan 30 2012. The links noted in the text are fairly standard stuff)
A 2009 study by the California Energy Commission concluded that the use of Keyline plows created the lowest carbon emissions from the subsoil and the addition of compost to grazing lands enhanced the carbon sequestration. This is an important finding because carbon sequestration, or the capture and removal of carbon dioxide from the atmosphere, is one of the methods to reduce carbon footprints and also a long-term solution to combat the accumulation of greenhouse gasses and global warming.
Regardless of the specific brand of plow used, the concept of the Yeoman's Plow and vertical tillage is a significant aspect of sustainable agriculture Keyline design, and holistic range management
